ABSTRACT
This study evaluated 52 dogs, which were male, intact, varied in age, of pure or mixed breed, with clinical signs suggestive of prostatic disease. Each individual underwent an ultrasound examination and fine-needle aspiration biopsy of the prostate gland for cytological evaluation. Benign prostatic hyperplasia (BPH) was the most frequent prostatic disease, followed by cystic benign prostatic hyperplasia, bacterial prostatitis, abscesses, cysts, adenocarcinoma, nonbacterial prostatitis and paraprostatic cysts. The highest frequencies of prostate disorder were found in mixed breeds, followed by poodles and German shepherds. Ultrasound examination allowed the determination of prostate size, as well as the visualization of the diseases affecting the gland, and was effective in guiding aspiration biopsy. The cytological evaluation of the gland, especially when associated with changes in ultrasound images, revealed the presumptive diagnosis of the condition.
